Turbomachine secondary seal assembly

摘要

An exemplary turbomachine secondary ring seal assembly (46) includes a base portion (66) that extends circumferentially about an axis (12) and a protrusion (68) extending from the base portion (66) toward the axis (12). The protrusion (68) has a sealing surface (70) that contacts a support to limit movement of a fluid from a first axial side of the base portion (66) to a second opposite axial side of the base portion (66). The sealing surface (70) faces the axis (12). The sealing surface (72) may also face in a radial direction.
